Title: Improvements in or connected with apparatus for use as a toy and for playing games
IPC: A63F9/02
Filed: 1922-12-27
Abstract: 209,930. Forbes, Sir C. S. Dec. 27, 1922. Games of chance. - In apparatus of the kind wherein a model aeroplane &c. rotates around a support and is provided with means for dropping a ball &c. into receptacles or upon targets, the ball-releasing mechanism is controlled bv the movements of a pendulum or gravity - actuated device displaced relatively to the body of the aeroplane by centrifugal action. The model aeroplane 10 is carried by a counterbalanced arm 11 secured to a sleeve 12 which fits loosely on a stationary spindle 13. Loose wheels 28 or other lost-motion mechanisms are carried by the. sleeve 12 and rest upon a disc 26 driven manually or by an electric or clockwork motor. The friction of the loose wheels 28 causes a gradual starting and stopping of the aeroplane when the disc 26 is started and stopped respectively. The wheels 21 of the aeroplane are attached to pivoted cage 15, Fig. 3, within the aeroplane. Centrifugal force swings the wheels outwardly relative to the body of the aeroplane and rotates the cage. A ball 29 resting on one bar 16 of the cage is thus allowed to fall, but is retained within the body of the aeroplane by a lower bar 16d until by the disconnection of the drive the aeroplane slows down and the ball falls from the aeroplane into one of a number of compartments 38, Fig. 1. Instead of a cage 15, the wheels 21 may rock an open-ended tube relative to pins on the aeroplane, or viceversa, in order to release the ball. In a modified apparatus the base board 14 is rotated in a direction opposite to the aeroplane by attaching the rotor of an electric motor to the base board and mountin the field magnets on the stationary base. The wheels 28 are then driven from the base. board and drive the sleeve 12 through a disc resting on the tops of the wheels. The apparatus may be operated by an alternating-current motor. In a modified arrangement for producing lost motion in the wheels 28, these, when being driven, screw along their spindles 27 against the resistance of coil springs which return the wheels after the drive has been disconnected. In a further modification, the wheels are connected to the foot of the sleeve 12 by elastic springs which are wound up and unwound when the drive is started and stopped.

Title: Improvements in and relating to timing apparatus
IPC: G04C23/34
Filed: 1945-12-31
Abstract: 613,123. Time alarm signals. TELEPHONE MANUFACTURING CO., Ltd., SMITH, S. J, and TERRY, R. ST. G. Dec. 31, 1945, No. 35254. [Class 118 (ii)] [Also in Group XXXVII] A timing mechanism for producing a sequence of operations of a switch comprises a rotating cylinder 29 having on its surface a helical fin 29a, and a disc 31 mounted on an axle at right angles to the axis of the cylinder the axle being mounted in a pillar 35 which can rotate about its own axis. Fixed to and projecting from the pillar 35 is an arm 39 which actuate the switch contacts when the pillar 35 is rotated. The disc 31 is rotated by pins 36 which project into the grooves formed by adjacent turns of the helix but do not extend to the bottom of the grooves. The disc also carries arms 31a corresponding to the days of the week and each arm from Monday to Friday carries at its tip a stud 37 which projects between the turns of the helix and rests on the surface of the cylinder. The cylinder rotates once in two hours and the helix has twelve turns so that each arm 31a traverses the cylinder in one day. The surface of the cylinder between the turns of the helix is provided at intervals with holes or depressions and with raised cam-like projections which cause the stud 37 to fall and rise as the cylinder 29 rotates and so causing the disc 31 to tilt one way or the other with a corresponding rotation of the pillar 35 and actuation of the switch through the arm 39. The same sequence of operations is repeated on each day from Monday to Friday. The arm corresponding to Saturday does not carry a stud at its tip but is provided with a depending portion which rides on the edge of the helical fin 29a which is formed with depressions and projections to produce a different set of operations from those produced from Monday to Friday. The stud &c. may be omitted from the Sunday arm so that no operation of the switch is produced. To enable the switch to be actuated for a definite interval of time during any period of a day a movable member may be provided which may be clipped over the helical fin at any position to form a cam surface to raise the arms 31a when they come into contact with the member. The tilting of the disc 31 may be used to actuate a relay to produce short operating impulses by means of a mercury switch for example. In order to compensate for any slight eccentricity in the mounting of the cylinder 29 a finger may be provided to ride on the edge of the cylinder and the switch contacts operated by a differential movement between the finger and the arms of the disc 31. The cylinder may be rotated by clockwork or synchronous motor or it may be given a step-by-step movement by pulses from a master clock. In Fig. 1 the cylinder is mounted on a shaft 13 to which is secured a ratchet wheel 16 which is given an intermittent motion by a pawl 17. The pawl 17 is carried by a pivoted lever assembly including a soft iron armature 25 which is attracted at intervals to the core of a relay 26 which is supplied with current pulses at predetermined intervals.

[Also in Group XIII] In a water-tube steam boiler the front and side walls, floor and roof of the furnace chamber 1 are lined with steam-generating tubes which extend between upper and lower drums 27, 28, the furnace being horizontally fired through the front wall by burners 15, 16 (and 17, 18, not shown in Fig. 1), the combustion gases discharging through a screen of generating tubes 33 defining the rear wall of the furnace and flowing serially through a pass 4A locating a convection superheater 5, a down-pass between baffles 35, 36 in which is disposed a group of generating tubes 34 and an up pass 37 housing a group of downcomer tubes, the gases discharging from the boiler through a breeching 38 and flowing downwardly through the tubes of an air heater 9 and through a duct 8 to an induced draught fan 6 whence they pass through a duct 11 to a stack 24. Combustion air passes from the air heater through a duct 47 to a wind-box 48 around the burners. To maintain a constant temperature of superheat, especially when the steam output falls, a duct 12 is provided to recirculate flue gas from duct 11 to the furnace, the duct connecting with a transverse duct 13 positioned below the furnace front wall. From respective ends of duct 13 a duct 14 extends upwardly adjacent each front corner of the furnace, the upper ends of ducts 14 being provided with dampers 23 and being interconnected by a cross duct 19. A slot 20 and slots 21, 22 disposed adjacent and parallel to the roof and sides of the furnace respectively connect ducts 19 and 14 throughout their lengths to the furnace chamber so that when gas is being recirculated it forms a moving blanket or screen over the roof and sides of the furnace, reducing the radiant heat transmission thereto so that the heat content of the gases flowing through the superheater pass is correspondingly increased. The recirculated gas flow is controlled by dampers 25, 26 in ducts 12 and 11 respectively, whilst the dampers 23 control the distribution of the gas in the furnace. Specification 721,155, [Group XIII], is referred to.
